Anti-theft brake or clutch pedal locking device

ABSTRACT

A device to lock a brake or clutch pedal of a vehicle so as to deter theft of the vehicle includes a base for placement on the floor of the vehicle beneath the pedal of the vehicle being locked and beneath a pedal shaft supporting the pedal. The device includes a generally U-shaped housing with a second leg attached to the base, a first leg shorter than the second leg, and a cross member connecting the first and second legs to define an opening between the first leg and the base and a slot between the first and second legs to receive the pedal shaft and permit travel of the pedal shaft through the slot. A locking mechanism includes a locking pin and a lock. The locking pin is selectively movable on the U-shaped housing between a raised locked position sufficiently close to a lower side of the pedal shaft to prevent the pedal shaft from being operably depressed, i.e., depressed sufficiently to enable the vehicle to be started or clutch or brake to be used and a retracted position to permit travel of the pedal shaft through the slot and opening. The locking pin is on the end of a rod which extends through the second leg and a housing of the lock fixed to the U-shaped housing above the second leg. A handle at an opposing upper end of the rod is pitched and shaped to deflect blows. The lock has an upper face with a key opening. The upper face faces substantially oppositely away from the base at a transverse angle to the base and to a perpendicular angle to the base. A barrel type key lock cylinder is used. The lock housing has multiple, mostly non-rectangular lateral sides to discourage cutting. The housings around the rod are made from hardened metals. The shorter, first leg is welded on its three outer sides to the cross member and is generally U-shaped with a deflection in its own cross wall for greater strength.

FIELD OF THE INVENTION

[0002] This invention relates to anti-theft brake or clutch pedallocking devices for vehicles which are particularly suitable for bothautomatic and standard transmission vehicles. More particularly, thisinvention relates to devices which prevent the brake or clutch pedalfrom being depressed, thereby rendering a vehicle inoperable.

BACKGROUND OF THE INVENTION

[0003] Automotive theft is a major worldwide problem. The U.S. FederalBureau of Investigation has reported that a car is stolen every 20seconds.

[0004] The proliferation of mechanical type anti-theft devices for motorvehicles have resulted in the commercial availability of different typesof anti-theft devices. One type of prior art system mechanically locksthe brake and accelerator by means of two independent or articulatedshoes which lock the pedals. The major problem stemming from the use ofsuch devices is that the driver has to reach out for the pedal area oractually get down on his or her knees in order to operate the lockingdevice, and the varying distance between the brake and accelerator whichcan prevent the device from being installed.

[0005] More recently, some devices have been suggested which areconstructed from a long rod consisting of an anti-picking material andwhich is provided at both ends with two shaped members that couplerespectively with a pedal and with the steering wheel of the vehicle.The coupling with the steering wheel is locked using a safety lock thatprevents the same from being disengaged. This device, which owing to itscharacteristics, can be employed on traditional transmission cars aswell as on automatic transmission vehicles, is affected in the main bytwo drawbacks.

[0006] First, the connection, due it longitudinal size andcumbersomeness is difficult to store when the device is not beingutilized. Secondly, devices of this nature actually have a poor recordagainst theft. Indeed, it is relatively easy to cut the rim of thesteering wheel by means of a saw or the like. The rim of the steeringwheel is usually not a viable obstacle for thieves, and the anti-theftdevice by can be disengaged merely pulling apart the two ends of therim. Such devices are also not usually adaptable for automatictransmission vehicles because of their structural characteristics.

[0007] In UK patent application No. 2,091,656, an anti-theftpedal-locking device for vehicles is described comprising a firstsupporting member extending upwards and provided with a safety lock andwith a laterally projecting member and a second supporting member, uponwhich the first supporting member slides. A projecting member cooperateswith the corresponding member of the first supporting member so as tolock a pedal of the vehicle when the latter member is in its lowerposition, while the lower end of the second supporting member may carrya base member to rest on the floor of the vehicle.

[0008] A number of United States Patents have also issued on brakelocking mechanisms. U.S. Pat. No. 4,040,675 discloses a vehicleanti-theft device which maintains the braking function of the brakingfluid by preventing reverse flow thereof from the wheel cylinder back tothe master cylinder until an authorized procedure permits said backflow.

[0009] U.S. Pat. No. 4,493,198 discloses an anti-theft lock for a pedaloperated apparatus. The invention incorporates first and second stopbodies which are arranged to clamp around the lever of a pedal. When thestop bodies are locked in place, the pedal cannot be operated unless theapparatus is restrained.

[0010] U.S. Pat. No. 4,934,492 discloses an automatic brake-lockingmechanism which locks the brake of a vehicle having a hydraulic brakesystem. The system incorporates a safety switch provided to operate inconjunction with the ignition switch so that the safety switch and theignition both must be operated to an “on” position to release theauxiliary brake device to allow normal operation of the vehicle.

[0011] U.S. Pat. No. 5,040,387 similarly discloses a vehicle brake lockassembly which engages a brake pedal and which includes a U-shaped endportion which engages the brake pedal telescopically to lock the brakepedal in position.

[0012] U.S. Pat. No. 5,345,796 discloses a vehicle brake-pedal lockingdevice which mechanically maintains the vehicle brake pedal in adepressed position to prevent the vehicle from being driven. The deviceincludes a horizontally and vertically pivoting brake-pedal swing arminterfacing structure.

[0013] Finally, U.S. Pat. No. 5,653,133 discloses an anti-theft devicefor vehicles having a steering wheel and a brake. The device comprises abrake guard moveably mounted to a fixed portion of the brake, a lowerelongated member which hooks to the brake guard, an upper elongatedmember which is locked to the lower elongated member, a wide bar spaceda distance adaptable to be placed around the steering wheel and alocking bar and a claw member. When the device is secured with twopadlocks, movement of the steering wheel and the brake pedal isprevented.

[0014] All of the above devices are so called active devices which mustbe actively placed on a vehicle. Passive alarms have also recentlygained popularity, but these devices are expensive and frequentlyactivate when a vehicle is accidentally struck. In addition to abovediscussed devices and technologies, the prior art also includes complextracking devices which send out signals to police if a vehicle isreported stolen. The search may take up to 24 hours or longer with noguarantee of recovery. Installation of these systems is expensive andrequire a monthly monitoring fee. Automotive alarms are similarlyexpensive and may be deactivated by car thieves.

[0015] While the prior art is replete with mechanisms and inventions forlocking the brake pedals of a vehicle, there is no simple and easysystem devised for swiftly securing the brake or clutch pedal in anon-depressible state without the driver or operator having to get downon his or her knees or crouch down. Such a system would be to disable avehicle, because many automobiles built since 1990 cannot start orcannot be placed into gear without the brake or clutch pedal beingdepressed.

[0016] The present invention is thus directed to a brake pedal or clutchpedal locking mechanism which does not require the driver or vehicleoperator to get down on his knees or to move beneath the vehicle andwhich prevents the brake pedal or clutch pedal from being depressed.These and other objects of the present invention will be described withreference to the following summary and detailed description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0038] The brake anti-theft device of the present invention is nowdescribed with reference to the enclosed Figures wherein the samenumbers are utilized where applicable. In general, the present inventionis a device specifically designed to lock the brake pedal or clutchpedal of a motor vehicle in an up, i.e., non-depressed, state.

[0039] Since 1990, many vehicles manufactured for sale in North Americacannot start unless the brake pedal of the vehicle is depressed. Invehicles with automatic-shifting transmissions, this feature is referredto as a “brake pedal shift interlock” or BPSI. Many non-automatictransmission, or “standard transmission” vehicles, have a similarfeature called the clutch pedal start interlock or CPSI, which requiresthat the clutch pedal be depressed before the vehicle can start. Thepresent invention is applicable to both types of vehicles. In essence,the invention is specifically designed to take advantage of the BPSI orCPSI by preventing the brake pedal of any vehicle, or the clutch pedalof a standard-transmission vehicle, from being operably depressed, i.e.depressed sufficiently to disable the CPSI or BPSI to thereby precludingstarting and/or driving of the vehicle. The present invention is alsodesigned to work on vehicles not having BPSI or CPSI, discounting theftmerely by preventing the brake or clutch pedal from being operablydepressed, thereby preventing the vehicle from being normally braked orits transmission shifted, respectively.

[0040] A particular feature of the present invention is that it isintended to be utilized by the driver or operator from the comfort ofthe driver's seat of the vehicle without any need for the driver to getdown on his or her hands or knees or to crouch in order to install oradjust the device. While the present invention will be described in thecontext of a conventional automobile it is to be appreciated that theteachings of the present invention are equally applicable to all mannerof vehicles having brake pedal or clutch pedal arms or shafts includingsport utility vehicles, vans, pick-up trucks and heavy trucks.

[0041] For purposes of explanation the present invention is nowdescribed in the context of a device which locks a brake pedal in anupward position, thus, for example, disabling the BPSI of the vehicle.Referring now to FIGS. 1 to 4, there is shown a first preferredembodiment of the brake or clutch lock anti-theft device 10 of thepresent invention having a base 12 which is configured for stableplacement on the floor of the vehicle adjacent to, i.e., beneath, thebrake pedal 11 and shaft 13 supporting the pedal 11. Use of a brakepedal 11 and shaft 13 is intended to be illustrative of the applicationof the present invention to either a brake pedal 11 or a clutch pedal(not shown) and is not intended to be limiting. The base 12 isconfigured to be placed flush to the floor of the vehicle directly belowthe brake pedal and pedal shaft 13 for stable support of the device 10

[0042] Extending from the base 12 is a generally U-shaped housing 14.The U-shaped housing includes a second leg 18 attached to the base 12, afirst leg 16 shorter than the second leg 18, and a cross member 36connecting the first and second legs 16, 18 to define a gap or opening20 between the first leg 16 and the base 12 and a slot 22 between thefirst and second legs 16, 18. The opening 20 facilitates the placementand removal of the brake pedal shaft 13. In a preferred embodiment, theslot 22 should have an approximate width of the pedal shaft 13 such thatthe pedal shaft 13 extends through the slot 22 and up to an extendedposition. In other words, the opening 20 and slot 22 are sufficientlylarge to receive the brake pedal shaft 13 and permit travel of the pedalshaft 13 through the slot 22. In the extended position, the brake pedal11 can be depressed freely as it extends downward through the slot 22.

[0043] The invention further comprises a locking mechanism indicatedgenerally at 32 associated with a second leg 18 of the U-shaped housing.The locking mechanism includes a lock 44 with a lock housing 46containing a lock cylinder 52. Extending between the second leg 18 ofthe U-shaped housing 14 and the lock 44 is a cylindrical tube 24. Thesecond leg 18, the cylindrical tube 24, and the lock housing 46 arepreferably a unitary assembly constructed from individual parts,preferably welded together. It will be recognized by those of ordinaryskill in the art that the cylindrical tube 24 need not be cylindrical,but may be any hollow structural member, including channel stock,box-section stock, etc. and that the second leg 18 and cylindrical tube24 can be made from a single piece (not shown).

[0044] The locking mechanism 32 also includes a slidable locking pin 26,which is provided at a first end of a rod 28 which passes through thecylindrical tube 24, second leg 18 and the lock housing 46. The rod 28also includes lock ratchets or serrations 30 preferably machined alongthe mid-section of the rod 28 to at least a point where the serrations30 pass through the lock housing 46 between both the raised and loweredor retracted positions of the locking pin 26. The second end of the rod28 preferably comprises a handle 34 which is used to pull the rod 28upward or push the rod 28 downward relative to the base 12. Thepreferred locking mechanism 32, which is utilized in the presentinvention may include a commercially available key operated steeringwheel lock cylinder including a movable latch member, which can bereleasably engaged with the serrations 30. Other locks are contemplatedfor the present invention including combination locks.

[0045] The locking mechanism 32 has both an unlocked state and a lockedstate. In the unlocked state, the rod 28 is free to slide through thelock housing 46. The unlocked state provides for installation andremoval of the anti-theft device 10 by permitting the rod 28 to bepositioned (i.e., retracted) such that the locking pin 26 does notobscure the opening 20 or slot 22. Preferably the locking pin 26 isfully received by the base 12 during installation and removal of thedevice 10 but it will be appreciated that full retraction of the pin 26will not always be required and that only partial retraction as shown insome later figures may be sufficient. In the locked state, the lock 44locks the ratchets 30 at the appropriate point as discussed more fullybelow. As shown most clearly in FIG. 4, as the rod 28 is moved in anupward direction, away from the base 12, the locking pin 26 enters theslot 22 and moves upwardly (Arrow A), thus securing the bottom of thepedal shaft 13 in an upward or unextended or inoperable position so thatthe pedal 11 cannot be operably depressed. Because the pedal 11 cannotbe operably depressed, the car cannot be placed in gear in vehiclescontaining BPSI, cannot be started in vehicles with CPSI, and invehicles with and without BPSI or CPSI, cannot be driven normally aseither the brake or clutch pedal 11 cannot be depressed to brake thevehicle or shift a standard transmission.

[0046] In the present description, several preferred embodiments will bediscussed. Each later-described preferred embodiment of the anti-theftdevice 10 has the same basic features as the previous preferredembodiments, so only particular additional or modified features as willbe discussed. Accordingly, descriptions of the features of thelatter-described preferred embodiments that are the same as those of theearlier-described preferred embodiments are not repeated. Instead,identical elements have been given identical element numerals throughoutand only the differences between the earlier-described preferredembodiments and the latter-described preferred embodiment will bedescribed, with numerals incremented by hundreds being used for new orrevised features of like elements.

[0047] A second preferred embodiment 210 of the present invention isshown in FIGS. 5 and 6. As shown in FIG. 5, the base 212 has three legportions 212 a, 212 b, and 212 c, configured in a generally T-shapedpattern. The advantage of a T-shaped pattern is that it provides greaterstability and maximum strength and support to the anti-theft device 210when installed, in addition to reduced weight, in comparison to thesolid rectangular base 12. The outboard ends of the leg portions 212 a,212 b, 212 c and the bottom of the first leg 216 suggestedly are beveledpreferably at 45 degree angles, so that the pedal shaft 13 can moreeasily be guided into and out of the slot 22 when the device isinstalled and removed from the pedal shaft 13.

[0048] The second preferred embodiment 210 further incorporates anelongated cross member 236 for enabling the driver to press the deviceinto the floorboard or carpet of the vehicle. The elongated cross member236 extends horizontally from the top of the first leg 216, thusproviding a sufficient surface area 238 for the foot of an operator topress downward. It is contemplated that the surface area 238 couldinclude a gripping top surface.

[0049] The second preferred embodiment 210 further incorporates studs240 which extend downward from the base 212 and which facilitate thepositioning and retention of the device 210 against a floor particularlya carpeted floor 235 in the vehicle. The studs 240 prevent the device210 from moving with respect to the floor. As shown in FIG. 7, a device110 may also incorporate cleats 142 which are cut into or otherwiseprovided in the bottom of the base 12. It is contemplated that acombination of studs 240 and cleats 142 could be used without departingfrom the scope and spirit of the invention. Lock housing 246 is smallerthan housing 46 and hangs the lock cylinder across rod 28.

[0050] The operation of the present invention is now described withreference to the enclosed figures and most particularly FIGS. 1 through4. The driver or operator desiring to utilize the device 10 (110 or 210)unlocks the device and lowers the pin 26 all the way down to the base 12(112, 212) by grasping the handle 34 and pushing the handle 34 towardthe base 12 (112, 212). The base 12 (112, 212) is then placed on thefloor 35 beneath the pedal shaft 13 which is located generally beneaththe steering wheel and steering column (neither shown in FIGS. 1-6). Thepedal shaft 13, is then passed through the opening 20 in the U-shapedhousing 14 (214) and into the slot 22 with the base 12 (112, 212)positioned squarely on the floor 35 of the vehicle. The operator thenpulls the handle 34 upwardly (Arrow A in FIG. 4), thus raising thelocking pin 26 upward into the slot 22 and securing the bottom of thepedal shaft 13 so as to lock the brake (or clutch) pedal 11, asappropriate, is in an upward position. As is shown in FIGS. 5 and 6, theoperator can place his foot on the surface area 238 of an elongatedcross member 236, if provided, to maximize the downward thrust of thedevice 210 against the floor 35 of the vehicle. If provided, the cleats142 and/or the studs 240 secure the device against the carpet or othersurface of the floor 35 beneath pedal 11. The vehicle operator thenlocks the device 10 (110, 210) in this position using the lock mechanism32 (232) such that the pedal 11 cannot be depressed, thereby disablingthe operation of the vehicle.

[0051] FIGS. 8-8B illustrate a third preferred embodiment device 310 ofthe present invention. In this embodiment, the first and second legs316, 318 are of substantially equal height and thus eliminate the needfor a base as shown and described with respect to the first and secondpreferred embodiments. The first and second legs 316, 318 are spaced atthe bottom to form an opening 320 which is tapered to slide over thepedal shaft 13, permitting the pedal shaft 13 to enter the slot 322,which begins at the narrow end of opening 320. The locking pin 326 ispulled upward by rod 328 thereby locking the pedal 11 and shaft 13 in anupward position as in the other embodiments described herein. The thirdpreferred embodiment 310 further includes two rotatable feet 342, whichare attached to the bottom of the first and second legs 316, 318 andwhich facilitate the pivotable support and positioning of the device310. The main attribute of this embodiment is to facilitate ease ofplacement of the device 310.

[0052] Referring now to FIGS. 9-13, there is shown an anti-theft device410 in accordance with a fourth preferred embodiment of the presentinvention. The locking mechanism 432 of the fourth preferred embodimentincludes a locking pin 426 and a lock 444. As with thepreviously-described preferred embodiments, the locking pin 426 is atone end of an elongated rod or shaft 428 (see FIG. 15) movable throughthe second leg 418 of the U-shaped housing 414 and the cylindricalhousing 24. The locking pin 426 is selectively movable on the U-shapedhousing 414 between a raised position shown in FIG. 13 and a retractedposition shown in FIG. 12. In the raised position, the locking pin 426is sufficiently close to a lower side of the pedal shaft 13 to preventthe pedal shaft 13 from being operably depressed, that is depressedsufficiently to enable the vehicle to be started and/or normallycontrolled. In the retracted position, the locking pin 426 permitstravel of the pedal shaft 13 through the slot 22 and opening 20. Thelocking pin 426 of the fourth preferred embodiment 410 embodies asignificant improvement over the designs of the first through thirdpreferred embodiments in that the upper, pedal shaft contacting surface426 a of the locking pin 426 is generally flat in a direction facing thepedal shaft 13. By providing a flattened shaft contact surface 426 a, alarger contact region between the locking pin 426 and the pedal shaft 13is created, thereby resulting in a more secure installation of theanti-theft device 410.

[0053] On the opposing end of the rod 428 from the locking pin 426 is ahandle 434, which differs from previous handles 34, 234, 334 of thefirst through third preferred embodiments in several ways. First, thehandle 434 is preferably threaded onto the rod 428. This is animprovement in security over prior designs, like embodiment 10, where anadhesive method of securing a smooth bored handle 34 to the end of asmooth rod 28 was employed. It is also contemplated that the handle 434could be further attached to the rod 428 by welding, brazing, or thelike, such that a secure, unitary structure is created preventing theunthreading of the handle 434 from rod 428. Second, the handle 434 isattached to the rod 428 at a non-perpendicular angle to the rod 428.This design presents a great advance in security over prior designs inthat where the handle 34 and rod 28 are joined in a perpendicular angle,a thief may use a hammer to strike the handle 34 in an effort to breakthe lock 44. Because the handle 34 was perpendicular to the rod 28, adirect blow to the handle 34 was readily achievable and the entire forceof the blow would be transmitted through the rod 28 to the lock 44,thereby defeating the lock 44. However, where handle 434 is at anon-perpendicular angle to the rod 428, a thief cannot achieve a directblow to the handle 434 or the top of the rod, parallel to the rod, asthe handle 434 will deflect at least a portion of the force of the blow.More preferably, the upper surface of handle 434 is smoothly curved andextends away from the base 414 in a generally convex shape to furtherdeflect impacts from directly above the rod 428. Third, the handle 434is made in one smooth piece without seams and with a smoothly varying,creaseless, seamless outer surface above rod 428, which does not haveany edges to be engaged by a tool (e.g. chisel, saw or drill).

[0054] Lock 444 is integrated into and is coupled to the U-shapedhousing 414 through cylindrical tube 424. Lock 444 includes a cylinder452 with the operative mechanical components in a housing or head 454.The lock 444 is operatively connected to the locking pin 426 to fix thelocking pin 426 in at least the raised position through engagement ofthe lock 444 and the serrations 30 of the rod 428. The lock 444 has anupper face 450 with a key opening 454. The lock 444 is preferably abarrel type with a circular key opening 454 accepting a cylindricallyshaped, barrel-type key 458 for greatly increased security in comparisonto standard blank-type (flat) keys (not shown). Barrel-type key locksare particularly resistant to being picked and to being broken withslide hammers. A sheet metal screw attachment is commonly fitted to theend of a slide hammer and is easily screwed into locks that acceptblank-type (flat) keys. The slide hammer is then used to pull the lockcylinder from its housing, thus defeating the security device. It ismuch more difficult for one to use this technique to defeat a lockhaving a circular key opening 454 and barrel-type key 458 as thesheet-metal screw attachment cannot readily be attached to such a lock.

[0055] Lock housing 446 extends from the top of cylindrical member 424in the direction of base leg portion 412 c towards the operator seatedin front of the device 410. The upper face 450 of the lock 444 and lockcylinder 452 faces substantially oppositely away from the base 412.Preferably the upper face 450 is pitched at an angle which is transverse(i.e. non-perpendicular and non-parallel) to a support plane defined bythe bottom of the base 412 (or more particularly, the bottoms of stud440 and cleats 442). The face is pitched downwardly from the plane ofthe base suggestedly at an angle of between about 15 and 30 degrees,more particularly between about 20 and 25 degrees. Orientation of theupper face 450, and hence the cylinder 452 in a direction substantiallyoppositely away from the base 412 obviates problems encountered withprevious locking anti-theft mechanisms where the locks faced in alateral direction (i.e., the first three embodiments). In using thoseprevious designs, if for example the lock faced leftwardly and theoperator was right handed, the operator had to use his or her off-handto operate the lock to fix the anti-theft device. The orientation of theupper face 450 of the lock 444 of the fourth preferred embodiment 410solves this problem by enabling the operator to use his or her dominanthand to fix the device 410 to the vehicle. Additionally, orientation ofthe upper face 450 in a direction substantially oppositely away from thebase 412 provides additional security with respect to cutting throughthe lock housing 446 with a saw. In prior designs like the first threeembodiments, where the lock housing 50 positioned the lock cylinder 52in a direction perpendicular to the rod 28, the side of the lock housing46 surrounding the lock cylinder 52 could readily be engaged by ahacksaw, thereby permitting one to cut through the lock 44 to defeat thedevice 10. Directing the upper face 450 oppositely away from the base412 eliminates any substantial upper surface to which one can engage ahacksaw and further serves to deflect blows delivered from above thedevice 410.

[0056] In the same vein, the lock cylinder 452 is protected by the lockhousing 446, which surrounds the lock cylinder 452. The lock housing 446preferably has more than four lateral sides. For example, eight lateralsides are depicted forming the perimeter of the upper face 450 in FIG.9. Only the side 438 a closest to rod 28 (FIG. 11) is rectangular. Theremaining seven lateral sides surrounding upper face 450 are triangularor trapezoidal. The only other rectangular lateral side is side 438 b(also FIG. 11). By providing more than four lateral sides 448, andparticularly non-rectangular sides, one is presented with greatdifficulty in perpendicularly engaging the intersection of the upperface 450 and the lateral sides 448 or any of the lateral sides 448directly with a hacksaw. A perpendicular engagement between a hacksawblade (not shown) and the surface intended to be cut is optimal forefficient cutting.

[0057] Suggestedly, lock 444 includes a separate latch member in housing446 which engages the serrations 30 of the rod 428 to secure the rod 428and locking pin 426. The latch preferably is spring loaded intoengagement with the serrations and is disengaged only by rotation of theinner member of the cylinder 452 turned by key 458. Thus, the latch isnot part of the cylinder but the cylinder 452 is need to disengage thelatch. Therefore, destruction of the cylinder 452, for example bydrilling it out, will not release the latch. The internal latch isfurther protected from attempting to freeze the cylinder to shrink it.

[0058] To further enhance the security of the lock 444, the lock housing446 is made from a tough material to prevent the lock 444 from readilybeing defeated by cutting or impact, preferably hardened steel. Tofurther increase security of the present invention, the legs 416, 418and cross member 436 of the generally U-shaped housing 414 andcylindrical tube 424 of the fourth preferred embodiment device 410 arealso made from similarly tough material, preferably hardened steel.While it is contemplated that other tough metals (e.g., stainless steel)could be employed without departing from the scope and spirit of theinvention, hardened steel provides an optimal balance between highstrength and thus security and expense.

[0059] As discussed above, the first leg 416 and second leg 418 of theU-shaped housing 414 are connected by cross member 436. In the fourthpreferred embodiment 410, the cross member 436 overlaps each of thefirst and second legs 416, 418 and presents lower edges 437 of the crossmember 436 overlapping the legs 416, 418 and which are welded to theupper sides of the first and second legs 416, 418 by welds 460 best seenin FIGS. 9-11. By overlapping the cross member 436 with the first andsecond legs 416, 418, rigidity of the first and second legs 416, 418 andthe U-shaped housing 414 is increased. Accordingly, security of theanti-theft device 410 is greatly increased. As shown in FIGS. 9 and 11,it is also preferred that the cross member 436 be welded at 460′ to thefirst leg 416 along the horizontal and two vertical interiorintersections of those two members to further increase structuralintegrity of the anti-theft device 410 and prevent the removal of thefirst leg 416 from the housing 414. Cross member 436 preferably extendsfully across second leg 418 and rod 428 is passed through the crossmember 436 to deter disassembly of housing 414.

[0060] It is suggested that at least one of the first and second legs416, 418 be modified from ordinary channel stock. Referring to FIG. 14,preferably first leg 416 is a generally U-shaped member (when viewed inaxial cross section) with opposing parallel arms 416 a, 416 b joined bya cross wall 416 c. Preferably, the cross wall 416 c has a deflection,preferably an outward bow 416 d between the pair of arms 416 a, 416 b,for increased longitudinal stiffness of the leg 416 (and/or 418) withrespect to ordinary channel stock. Forming at least one of the first andsecond legs 416, 418 as a generally U-shaped member like member 416 withbowed or otherwise stiffened cross wall overcomes a significant drawbackof prior designs that employed simple channel stock of three straight,perpendicular walls to form the first and second legs 16, 18. Thelongitudinal stiffness of straight sided channel stock is significantlylower than that of the U-shaped configuration with a deflected crosswall 416 c. It is correspondingly easier to defeat a security devicehaving first and second legs 16, 18 mace from simple channel stocksimply by bending the first leg 16 such that the pedal shaft 13 can beremoved from the slot 22 between the pin 26 and the bent leg 16. It isalso contemplated that other cross sectional shapes of the leg 416 andof the walls 416 a, 416 b and/or 416 c in particular could be used toform the first or first and second legs 416, 418 for increased strengthwithout departing from the spirit and scope of the present invention.

[0061]FIG. 15 depicts rod 428 with serrations 30, locking pin 426 andhandle 434. Preferably the rod 428 and pin 426 are formed from a singlepiece of hardened steel. As mentioned earlier, handle 434 is separatelyformed from a single piece of tough material, preferably forges fromhardened steel, and threaded onto rod 428.

[0062] Any of the anti-theft devices 10, 210, 310, 410 can be combinedwith a banner configured for attachment to the vehicle to announce theuse of the device. As shown in FIG. 16, the banner 62 preferably is acover configured for attachment to the steering wheel 64 of the vehicle.The banner 62 preferably has a logo 64 or other identifying indicia toinform would-be thieves that the vehicle is immobilized through use ofthe anti-theft device 10, 210, 310, 410. In this way, notwithstandingthat the anti-theft device is not readily visible because it is usedbelow the steering wheel and dashboard in the leg compartment of thevehicle, a would-be thief would likely not forcibly enter the vehicleonly to discover after having caused substantial damage to the vehiclethat his or her efforts would be futile. The banner need not be attachedto the steering wheel 64 of the vehicle, but can be configured to bemounted in any visible location, such as on the interior surface of thewindshield 68 or another window, on the dashboard 70, or hanging from arearview mirror 72.

[0063] It is to be appreciated by those skilled in the art that thedevice of the present invention may include a protective outer coatingcomposed of vinyl, PTFE, rubber or plastic.

[0064] The present invention has been described with reference to apreferred embodiment. It is to be appreciated that other embodimentsfulfill the spirit and scope of the present invention and that the truenature and scope of the present invention is to be determined withreference to the claims appended hereto.
